Abstract :
The authors extend existing supervised-learning and unsupervised-clustering algorithms to allow document classification based on the information content and temporal aspects of news events. They´ve adapted several IR and machine learning techniques for effective event detection and tracking. The article discusses our research using manually segmented documents
